Effect of pH on Enzyme Productivity Purpose: The purpose of this experiment is to determine how the acidity and basicity of the environment affects the rate at which a specific enzyme is able to produce products in a computer simulation. Background Information: An enzyme is a protein which serves as a biochemical catalyst. An enzyme increases the likelihood of a collision between reactants that result in a successful reaction, in which substrates become the product. However, enzymes are not necessary

Abstract Enzymes are organic catalysts that can help speed up chemical reactions (enzymes function p57). There are very few exceptions, however all enzymes are proteins. Every enzyme is specific to a certain chemical reaction depending on its substrate as well as amount (enzyme function p57). Enzymes must maintain a specific structure so that they can work properly. If an enzyme's structure is changed by chemicals or heat it may not be able to function at all. Introduction A metabolic

Enzymes Enzymes are complex proteins that carry out essentially every chemical reaction in the human body. Enzymes function as biological catalyst, regulating the rate at which chemical reactions proceed without themselves being altered in the process. In this particular experiment we recognized benzoquinone and examined two numbers of factors to determine their effects on enzyme action. The factors were temperature and

The purpose of immobilising enzymes before they are used to catalyse a reaction is to be reused again because they are not completely lost in the solution. We immobilised lactase enzyme by dissolving it in sodium alginate gel. This is one of the more widely used practises in industry as it is very efficient and effective. We can see that by our experiment by immobilising the enzyme and could retain it even after it has been involved in the reaction by catalysing the breakdown of lactose in glucose

Introduction An enzyme is a catalytic molecule that speeds up reactions to a rate that limits at equilibrium. When a substance is going to have a reaction, it will require a activation energy and the enzyme lower that activation energy. The ability to do this comes from the substrate that the enzyme contains. In the enzyme molecule, there are active sites where it can interact with a substrate and then catalyzes reactions. The enzyme activity is affect by its surroundings especially when pH, temperature

An enzyme is a “macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction,” (Campbell Biology, 68). There are many different enzymes that have varying effects on reactions. Catalase, “an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen,” is the primary enzyme that effects hydrogen (Encyclopedia Britannica). In this experiment, the goal is to test how three different locations where these enzymes can be

Introduction Enzymes can be defined as substances that are produced by act as catalysts and they look to bring a reaction, (Cooper, 2000). Various pH levels affect enzymes. This experiment will show how pH levels affect the enzyme catalase process, (Daniel, Michelle, & Danson, 2010). This experiment will look to measure the acidic fluid. The enzymes that are being used in this experiment are pieces of chicken liver and the acid being used is hydrogen peroxide. Goal The goal of this experiment

Enzymes Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. They are a class of proteins that have a unique three dimensional structure that allows it to bind with a specific substrate to facilitate a reaction. Many biological reactions will not occur spontaneously in the cell; there is simply not enough energy for the reaction to take place. Enzymes make these reactions possible by lowering the reactionÂ’s

What is the effect of temperature, pH, and substrate concentration on Enzyme activity? Purpose: Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzymes have only one substrate that breaks down. Enzymes are produced in the cells of the body and affect the rate of almost all the chemical reactions which take place in living organisms. The rate of enzymes activity is influenced by temperature, pH, and substrate concentration

Enzymes are proteins that catalyze (speed up) biological reactions in an organism by lowering the activation energy of a reaction. They do this by either straining the bonds in a molecule so that is easier to break up or by placing separate molecules/elements close to each other so that bonds are formed. Enzyme activity is influenced by an array of different factors such as enzyme concentration, substrate concentration, temperature, pH and inhibitor concentration. All of these affect the rate of
